I will design rf pcb antenna impedance matching and 50 ohm layout

If your WiFi, Bluetooth, LoRa, or GPS device has poor range or fails certification, the problem is usually impedance mismatch or bad RF routing not the antenna itself. I design controlled 50-ohm traces, matching networks (L-match, Pi-match), and clean RF layout to get your existing or new antenna performing correctly.

This gig is for people who already have hardware and a specific RF problem: weak signal, failed FCC/CE pre-scan, or an antenna that "should work" but doesn't. I'll review your schematic/layout, identify the routing or matching issue, and deliver a corrected layout with a matching network calculated for your exact antenna impedance.
